La figura 1 explica la estructura del dispositivo de acuerdo con la invención o bien de los aparatos de control de acuerdo con la invención en la medida que es necesaria para la comprensión de la invención. Es decir, que en el presente caso para mayor claridad los componentes necesarios, pero que no son imprescindibles para la comprensión de la invención. Un primer aparato de control SG1 presenta como elemento central un microcontrolador \muC, que sirve como circuito de evaluación. El microcontrolador \muC, que puede ser sustituido también por otros tipos de procesador o ASICs o circuitos de evaluación de estructura discreta, está conectado a través de una entrada/salida de datos con una memoria S1 asociada, que posibilita una memorización duradera o bien volátil de datos. El microcontrolador \muC recibe a través de una interfaz IF1 datos desde una instalación de detección de impacto CS transferida. Adicionalmente, una instalación de detección de impactos puede estar presente también dentro del aparato de control SG1. También puede estar presente una instalación de detección del entorno o bien una instalación de detección para la detección del ocupante. La instalación de detección del impacto CS presenta sensores de aceleración en la parte delantera del vehículo y en los lados del vehículo y puede presentar adicionalmente sensores de presión en la zona de las partes laterales del vehículo, para detectar lo más rápidamente posible un impacto lateral. También se puede utilizar una instalación de detección de sonido corporal como instalación de detección de impacto CS. También son posibles otros sensores de contacto. Como sensores de entorno se pueden utilizar, además de una instalación de detección de radar y de ultrasonido, también una instalación de detección de vídeo o una instalación de detección Lidar o un Dispositivo Fatanic Mixing. La instalación de detección de la aceleración y la instalación de detección de la presión están constituidas habitualmente con medios micromecánicos. Es decir, que modificaciones de la presión y las aceleraciones se manifiestan en un movimiento de un elemento fabricado con medios micromecánicos, que con frecuencia se expresa entonces en una modificación de la capacidad. Esta modificación de la capacidad se convierte en una tensión, que en último término es digitalizada y de esta manera se puede transmitir como dato a la interfaz IF1 en el aparato de control SG1. La transmisión entre la interfaz IF1 y el microcontrolador \muC se realiza habitualmente a través del Bus de Interfaz Periférica en Serie, llamado de forma abreviada SPI. N función de estos datos de los sensores, el microcontrolador \muC calcula por medio de un algoritmo de activación, que carga desde la memoria S1, si debe realizarse una activación de los medios de protección de personas PS y del asistente de freno BA. Si el microcontrolador \muC llega entonces a una decisión de activación, entonces activa igualmente a través del bus SPI un circuito de encendido FLIC, que deja pasar la corriente de encendido hacia los medios de protección de personas. La corriente de encendido se obtiene habitualmente de una reserva de energía, es decir, desde uno o varios condensadores o desde la batería del vehículo.Figure 1 explains the structure of the device according to the invention or of the apparatus of control according to the invention as necessary for the understanding of the invention. That is, in the present case for clarity the necessary components, but which are not essential for the understanding of the invention. A first control apparatus SG1 presents as a central element a microcontroller µC, which serves as an evaluation circuit. He microcontroller µC, which can also be replaced by others processor types or ASICs or structure evaluation circuits discrete, it is connected through data input / output with an associated S1 memory, which allows memorization durable or volatile data. The microcontroller receives through an IF1 data interface from an installation of CS impact detection transferred. Additionally, an installation impact detection may also be present within the control unit SG1. An installation may also be present. environment detection or a detection facility for occupant detection The installation of impact detection CS presents acceleration sensors at the front of the vehicle and on the sides of the vehicle and can present additionally pressure sensors in the parts area side of the vehicle, to detect as quickly as possible a lateral impact You can also use an installation of body sound detection as a detection facility for CS impact. Other contact sensors are also possible. How environment sensors can be used in addition to an installation of radar and ultrasound detection, also an installation of video detection or a Lidar detection facility or a Fatanic Mixing device. The detection facility of the acceleration and pressure detection installation are usually constituted with micromechanical means. That is Pressure changes and accelerations are manifested in a movement of an element made with micromechanical means, which is often expressed then in a modification of the capacity. This capacity modification becomes a tension, which is ultimately digitized and in this way it can transmit as data to the IF1 interface in the device SG1 control. The transmission between the IF1 interface and the microcontroller [muC] is usually performed through the Bus Serial Peripheral Interface, called abbreviated SPI. N function of this sensor data, the microcontroller \ muC calculates by means of an activation algorithm, which loads from the memory S1, if an activation of the means of protection of people PS and brake assistant BA. If he microcontroller? then reaches an activation decision, then it also activates through the SPI bus a circuit of FLIC ignition, which lets the ignition current pass to the means of protection of people. The ignition current is usually obtained from an energy reserve, that is, from one or more capacitors or from the vehicle's battery.
No obstante, la decisión de activación es transmitida adicionalmente a través de otra interfaz IF2 desde el microcontrolador \muC hacia un aparato de control SG2 en forma de al menos dos mensajes, de manera que el aparato de control SG2 puede activar de manera correspondiente un asistente de freno BA. La interfaz IF2 puede ser un controlador CAN, de la misma manera entonces la interfaz IF3, de manera que un bus CAN establece la comunicación entre los dos aparatos de control SG1 y SG2. No obstante, también son posibles otros métodos de transmisión de datos como una comunicación punto-a-punto u otros sistemas de bus. La interfaz IF3 en el aparato de control SG2 transmite los mensajes al microprocesador \muP en el aparato de control SG2. En lugar de un microprocesador \muP, también es posible utilizar igualmente un microcontrolador u otros circuitos de evaluación. También el microcontrolador \muP utiliza una memoria S2, para memorizar datos de forma duradera o bien volátil o bien para cargarlos desde la memoria duradera. El microprocesador \muP, cuando los al menos dos mensajes del aparato de control SG1 han llegado al aparato de control SG2, activa de manera correspondiente el asistente de freno BA a través de la interfaz IF4.However, the activation decision is additionally transmitted through another IF2 interface from the microcontroller? towards a control device SG2 in the form of at least two messages, so that the control device SG2 You can activate a BA brake assistant accordingly. The IF2 interface can be a CAN controller, in the same way then the IF3 interface, so that a CAN bus establishes the communication between the two control devices SG1 and SG2. Do not However, other methods of transmission of data as a communication point-to-point or other systems of bus The IF3 interface on the control device SG2 transmits the messages to the microprocessor? in the control device SG2. In instead of a microprocessor, it is also possible to use also a microcontroller or other evaluation circuits. The microcontroller also uses an S2 memory to memorize data in a durable or volatile way or to Load them from lasting memory. The microprocessor, when the at least two messages of the control device SG1 have arrived at the control device SG2, activates accordingly the BA brake assistant via the IF4 interface.
Esta decisión de activación desde el aparato de control SG1 se puede transmitir a varios aparatos de control. Pero el aparato de control SG2 puede utilizar, además de esta decisión de activación, también otros datos evaluados por sí mismo, para decidir si y cómo debe activarse la instalación de actuación correspondiente, aquí el asistente de freno BA.This activation decision from the device SG1 control can be transmitted to various control devices. But the control device SG2 can use, in addition to this decision of activation, also other data evaluated by itself, to decide if and how the performance installation should be activated corresponding, here the brake assistant BA.
La figura 2 explica en un primer ejemplo de realización una transmisión posible de la decisión de activación con al menos dos mensajes. En el aparato de control SG1 se transmite desde un bloque 20, que es aquí un elemento de software, un mensaje N1, que desplazar al aparato de control SG2 a un estado activo. Después de que ha transcurrido un tiempo, el elemento de software 21 genera el mensaje N2, que contiene la decisión de activación propiamente dicha. El aparato de control SG2 verifica a la recepción del mensaje N2, si ha transcurrido o no el tiempo durante el que el aparato de control SG2 puede permanecer en el estado activo. Si éste no ha expirado y el mensaje N2 contiene la decisión de activación, entonces se realiza la activación de la instalación de actuación BA. En lugar de dos mensajes, se pueden utilizar también tres o más mensajes, que controlan diferentes fases de la activación del aparato de control SG2. Los elementos de software 20 y 21funcionan como módulos en el microcontrolador \muC. Están incrustados en el software general del microcontrolador \muC.Figure 2 explains in a first example of possible transmission of the activation decision With at least two messages. The control unit SG1 transmits from a block 20, which is here a software element, a message N1, which move the control device SG2 to an active state. After some time has elapsed, the software item 21 generates message N2, which contains the activation decision proper. The control device SG2 verifies reception of message N2, whether or not the time has elapsed during which the SG2 control device can remain in the active state. Yes this one has not expired and message N2 contains the activation decision, then the activation of the actuation installation is carried out BA. Instead of two messages, three or more can also be used messages, which control different phases of the activation of the SG2 control device. Software elements 20 and 21 work as modules in the microcontroller \ muC. They are embedded in the general microcontroller software.
Esto se aplica también para el ejemplo de realización de acuerdo con la figura 3. El aparato de control SG1 presenta dos módulos de software 30 y 31, que generan en cada caso el primero y el segundo mensaje. Aquí a través del módulo de software30 se transmite el mensaje N1, que contiene ya la decisión de activación. El aparato de control SG2 requiere ahora con un mensaje N3 propio desde el aparato de control SG1 una activación de esta decisión de activación. A continuación, el módulo de software 31 emite una confirmación de esta decisión de activación al aparato de control SG2. También aquí se espera un tiempo entre la entrada de los mensajes N1 y N2, que no puede exceder un valor determinado predefinido. Si se excede este valor, no se produce ninguna activación. Este método se podría asegurar adicionalmente también aquí a través de otras confirmaciones. También es posible combinar los ejemplos de realización según las figuras 2 y 3 entre sí.This also applies to the example of embodiment according to figure 3. The control device SG1 presents two software modules 30 and 31, which generate in each case The first and the second message. Here through the module software30 the message N1 is transmitted, which already contains the decision of activation. The SG2 control device now requires a own N3 message from the control device SG1 an activation of This activation decision. Next, the software module 31 issues a confirmation of this activation decision to the device SG2 control. Also here a time is expected between the entry of messages N1 and N2, which cannot exceed a certain value predefined If this value is exceeded, none is produced activation. This method could be additionally ensured as well. here through other confirmations. It is also possible to combine the embodiments according to figures 2 and 3 with each other.
La figura 4 explica en un diagrama de flujo el desarrollo del primer ejemplo de realización de acuerdo con la figura 2. En la etapa del procedimiento 400 está presente una decisión de activación, que ha sido formada en el aparato de control SG1, para el aparato de control SG2. En la etapa del procedimiento 401 se transmite a continuación el mensaje N1 al aparato de control SG2 con la encargo de desplazarse a un estado activo. En la etapa del procedimiento 402 se verifica si ha entrado un segundo mensaje N2 hasta una duración de tiempo máxima \deltat. Si éste u otro mensaje no han entrado, entonces se salta a la etapa del procedimiento 404 y se lleva a cabo una reposición del aparato de control SG2 a un estado inactivo. Sin embargo, si se ha recibido el mensaje N2 dentro del tiempo \deltat por el aparato de control SG2, se lleva a cabo en la etapa del procedimiento 403 la activación del asistente de freno BA. De manera alternativa, se puede realizar la activación de otros dispositivos de actuación, como se ha representado anteriormente.Figure 4 explains in a flow chart the development of the first embodiment according to the Figure 2. In the step of the procedure 400 a activation decision, which has been formed in the apparatus of control SG1, for the control device SG2. In the stage of procedure 401 is then transmitted message N1 to SG2 control unit with the task of moving to a state active. In the step of the procedure 402 it is verified if it has entered a second message N2 up to a maximum duration of time \ deltat. If this or another message has not entered, then skips to step 404 and a reset is carried out of the control device SG2 to an inactive state. However, if received the message N2 within the time \ deltat by the control apparatus SG2, is carried out in the stage of procedure 403 the activation of the BA brake assistant. From alternatively, the activation of others can be performed actuation devices, as depicted previously.
La figura 5 muestra en otro diagrama de flujo el desarrollo del procedimiento de acuerdo con la invención según el segundo ejemplo de realización. En la etapa del procedimiento 500 se forma la decisión de actuación en el aparato de control SG1 en función de las señales de los sensores de la instalación de detección de impacto CS. A continuación, en la etapa del procedimiento 501 se transmite el mensaje N1 al aparato de control SG2 con el contenido de que debe realizarse una activación del asistente de freno BA. El aparato de control SG2 emite a continuación una solicitud N3 al aparato de control SG1, para que confirme el mensaje N1. Esto se verifica entonces en la etapa del procedimiento 503, si el mensaje N2 ha entrada como confirmación dentro del tiempo \deltat en el aparato de control SG2. Si se ha establecido este mensaje N2 dentro del tiempo \deltat en el aparato de control SG2, entonces se realiza en la etapa del procedimiento 504 la activación del sistema de actuación correspondiente, aquí del asistente de freno BA. Si dentro del tiempo \deltat no ha llegado el mensaje N2 o ha llegado otro mensaje, entonces se realiza en la etapa del procedimiento 505 el final del procedimiento de acuerdo con la invención.Figure 5 shows in another flow chart the development of the method according to the invention according to the Second embodiment.
